Dicyclohexyl(2′,2′′,4′,6′-tetramethyl[1,1′:3′,1′′-terphenyl]-2-yl)phosphine CAS 1668597-95-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dicyclohexyl(2′,2′′,4′,6′-tetramethyl[1,1′:3′,1′′-terphenyl]-2-yl)phosphine.

Dicyclohexyl(2′,2′′,4′,6′-tetramethyl[1,1′:3′,1′′-terphenyl]-2-yl)phosphine (CAS 1668597-95-2), molecular formula C34H43P and molecular weight 482.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Dicyclohexyl(2′,2′′,4′,6′-tetramethyl[1,1′:3′,1′′-terphenyl]-2-yl)phosphine (C34H43P) is characterized by organophosphorus functionality, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Dicyclohexyl(2′,2′′,4′,6′-tetramethyl[1,1′:3′,1′′-terphenyl]-2-yl)phosphine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
